Walkthrough

The changes extend the functionality of the ovos_persona_server by introducing several new API endpoints. The modifications add new import statements and methods for handling chat completions and prompt generation. Specifically, the endpoints /api/chat, /api/generate, and /api/tags have been added or updated. The existing chat_completions function was modified to integrate these new interactions using a session management component. Overall, the updates enable support for streaming responses and introduce compatibility with multiple APIs.

Poem

I’m a hopping rabbit in a code-filled glade,
API endpoints bloom where new features are laid.
Chat and generate now share the stream,
Tags reveal secrets in a structured dream.
With sessions and bytes, I leap with glee—
Celebrating code with a joyful spree!
🐇🌟

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
